I plan on vanity mining addresses soon, and I'm looking to purchase a single GPU that will give me the most MKeys/s. I'm currently aiming to get the HD 5870.

I've looked around and it seems that the HD 5870 gives up to 30 MKeys/s.
There is only one big informative thread and it seems that someone overclocked/configured a 7xxx card to get 50 MKeys/s, but no direct mention of which card in the post or what the settings were (can't find the post at the moment).
Then there's a claim that the HD 5970 can get ~40MKeys/s, but it's a single post with no other sources/statements.

Has anyone thoroughly researched vanity mining to see which card would hash the fastest?

Bump!

No clue, but I would suspect that its all going to fall in line with the same hashing power as anything.  A 5870<5970<7xxx, for the most part.  Just check out a mining comparison chart for bitcoin hash power and see how one card hashes over another.  If you know a 5870 is good for about 30, then you can calculate the others off of that depending on the % increase or decrease in hashing power you see on comparison charts.

Been proven completely false...

When i started to get into this mining there was the 5xx0 and 6xx0 cards. Most of the people who compared them said the 5870 cards are most effective (Mh/watt) than the other models. I went with their recommendation...
Now i am finishing with the gpus. If you need some cards or mb let me know :)

What are your settings for 7xxx? Been a while since I ran vanitygen, but I'm pretty sure I was getting something like 170 mkey/sec with 3 5970s (56.66 mkey per card)

what 5870 do you have? my 5870 gets 12.5 Mkey/s

I believe the highest anyone got a 7xxx running was about 50, with TONS of tweaked settings. What were your settings?

Reference. I haven't actually tested it yet, waiting on a SATA to MOLEX connector. I believe there are settings available to get a 5870 to 30 MKeys though.

Ok. I probably have a faulty 5870 because when I push it higher than 64 threads in the software, which pulls 12.5 Mkey, it causes the drivers or system to fail and reboot. Would a 7870 or 7970 be better though?

What driver version are you using?  As proven by my earlier post, I have no clue about vanity keys.  I know when they first came about I messed around with it for like a day but then left it alone as I didnt want my GPUs not to be mining. Now, I could probably do it.  A couple of 5830's and a 5870, would let them do their work and make a key or two.

Anyway, back to the topic at hand.  The reason I ask the driver question is because if its anything like mining, driver versions are a big part of it.  I know 5xxx series cards like 11.11 or 11.12 drivers.  Anything above that it actually starts taking performance hits.

Not sure if "advertising" is allowed here or not, but I recently stopped mining on my 5870 and I'm selling on ebay if you fancy a punt. I mention it not so much to make money off the card from someone here, but I'd rather it goes to someone as a miner piece of hardware rather than "Joe public" who'd probably use it as a GPU. Most of them go for 70-80 euros as a guideline, but I don't have a reserve set.

Gave up the 5870 as a means to mine as the bitcoin/watt equation isn't great anymore unless you have free power. I did overclock the puppy and it was stable at 950mhz, so you should get good returns on it doing some non-bitcoin mining
